[FFmpeg-devel] [PATCH] [PATCH] avcodec: Add more kCVImageBufferColorPrimaries to videotoolboxenc

[Nomis101]

Videotoolbox currently only supports the color primaries gamut ITU R 709 and 2020. This patch adds support for EBU 3213 (PAL video) and SMPTE C (standard definition video). That is importand for video
convertion applications, based on FFmpeg. Would be nice to get this reviewed.
